REVOLVING HEEL.

Specification of Letters Patent.

Patented Oct. 25, 1921.

Application filed September 28, 1920. Serial No. 413,295.

To all whom it may concern:

Beit known that I, TOWNSON HAND, a citizen of the United States, and a resident of New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Revolving Heels, of which the following is a specification.

The invention relates to the class of boots and shoes, and more particularly to an improved mounting for revolving heels.

The object of the invention is to provide a mounting for revolving heels which can be applied to shoes without requiring the ordinary leather heel, which is capable of application by one inexperienced as a cobbler, the device being capable ofbeing readily changed from one shoe to another when the shoe is worn out, as well as permitting the renewal of the revolvingfcushion or tread portion of the heel, in addition to securing uniform wear and proving durable andsatisfactory in use. i r

With the above and other objects in view the invention consists in certain novel combinations and arrangement of parts as will hereinafter be more particularly pointed out and claimed.

In the accompanying drawings:

Figure 1 is a fragmentally perspective view of a shoe inverted and having the im proved revolving heel applied-thereto.

Fig. 2 is an enlargedsectional 'view of the revolving heel applied to a shoe, the latter being shown in dotted lines.

Fig. 3 is a cross sectional view of the revolving tread portion of the heel.

Fig. 4 is a detail perspective View of a metallic lock washer employed with the device, and

Fig. 5 is a perspective bottom view of the heel plate for mounting the tread;

Referring to the drawings in detail, in which like reference characters designate corresponding parts throughout the several views the improved revolving heel is shown as em odying a plate 10 shaped to conform to the heel portion of the shoe designated at 11. For this purpose, the sole 12 is allowed to remain, the usual leather heel being removed or omitted. The plate 10 is heel shaped, as above specified, and terminates beneath the arch of the shoe. The sole is set in this plate which is preferably of aluminum or other suitable material and provided with raised edge portions or edges 13 forming a rim or flange except at the front straight edge portion 14, said plate also tapering in thickness toward its forward edge, as clearly shown in Fig. 2 of the drawings. This plate is further provided with a series, preferably five openings 15 properly spaced apart to receive screws or other securing means 16, by which the plate which forms the mounting for the tread portion or cushion of the heel, is detachably secured in position. By this means, the plate can be readily applied or removed so that it may be taken from a worn out shoe and changed to another one in short notice and quickly, by one even though inexperienced in the art of a cobbler.

The tread plate 10 is further provided with a central circular raised boss 17 which is provided with a threaded passage 18 extending through the plate, said boss having diametrical depressions or grooves 19 upon opposite sides of the threaded opening 18, the purpose of which will be hereinafter 'more fully-set forth. The heel or cushion roper is designated 20, and is of circular outline and preferably enlarged toward its base portion, the bottom face being dished out or rendered concave as indicated at 21 and the plate 22 being molded or vulcanized within the rubber forming the cushion to. reinforce the same and to facilitate the mounting.

As shown, the tread portion 20 is provided with a central opening 23 engaging the boss 17 revolubly, while the plate 22 is centrally apertured as indicated at 2 and pressed upwardly to provide a relatively funnel shaped or conical portion 25 within the aperture 23 so that the edge of the opening is adapted to engage the bottom face of the boss 17. On the raised boss or projection, the heel is adapted to revolve, the same being of rubber or other suitablejcushioning material or leather, the revolving action insuring uniform wearing of the tread portion and thus provide a heel which will be durable and lasting and which will wear evenly and uniformly during use, both for the purpose of increasing its length of life and preserving generally the appearance throughout such life. A washer 26 is fitted within the conical portion 25 of the plate 22 from beneath, and also fits within the aperture 23 of the tread portion 20 by reason of its cylindrical portion 27 at the lower end thereof. This washer is made to conform to the plate 22 and is also countersunk at the inside, while at its upper edge, there is provided at each side a projection 28, the two projections being adapted to engage the depressions 19 in the boss 17, thereby holding the washer stationary when held in place by a screw 29 which engages the threads 18. The projections 28 in engagement with the depressions 19, serve to retain the washer against rotation, thus affording a locking device to prevent the screw 29 from turning and working loose, thus insuring the retention of the tread portion on its mounting. It will also be apparent that the rubber or other suitable material forming the tread portion revolves by the act of walking, thus insuring uniform wear and preventing the shoe from wearing over at the heel. When the heel is worn down, with the means of a screw driver, the same can be easily removed and a new one replaced in an instant. The heel is capable of being quickly attached, although nails may be used instead of screws, and will be found strong and durable.

Having thus described the invention, what I claim is:

1. A revolving heel comprising a plate adapted to conform to the heel of the shoe and providedwith a raised edge portion at the sides and back extending in a continuous unbroken line, said plate having a plurality of openings therethrough to receive securing means for securing the same against the bottom of the shoe, said plate having a central circular boss projecting therefrom provided with end depressions and a threaded aperture, a cushion heel tread of circular outline having a reinforcing plate and a central aperture in which said plate is extended and bent into conical form to engage the bottom of the boss, a washer fitted into such conical portion and aperture and having projections engaging said depressions on the boss, and ascrew having its head embedded in the washer and engaging the threaded aperture of the boss and plate to detachably secure the tread in position.

2. A revolving heel comprising a tread mounting including a plate having means for securing the same against the shoe at the heel portion thereof, said plate having a projecting boss provided with a central threaded aperture and having depressions diametrically on the lower end thereof, a downwardly enlarged circular heel tread having a bottom concavity, a flatplate embedded in said tread, said tread having a central circular aperture into which said plate extends for contact with the bottom end of the boss and revolubly mounted thereon, a washer fitting said aperture and disposed against said plate, said washer having projections cooperating with the depressions to prevent rotation of the washer, and a screw having its head seated inrthe washer flush with the face of the concavity and detachably engaged in the threaded aperture of the plate.

3. A revolving heel comprising a plate adapted to conform to the .heel of the shoe, said plate having a plurality of openings therethrough to receive securing means for securing the same against the bottom of the shoe, said plate having a central circular boss projecting therefrom provided with end depressions and a threaded aperture, a cushion heel tread of circular outline having a reinforcing plate and a central aperturein which said plate is extended and bent into conical form to engage the bottom of the boss, a washer'fitted into such conical portion and aperture and having projections engaging said depressions on the boss, and a screw having its head embedded in the washer and engaging the threaded aperture of the boss and plate to detachably secure the tread in position.
